After coming back recently, it feels like I'm getting Treasure Vaults on every random floor that I go to.
No elevator costs = you do more levels = you'll find more treasure vaults anyways.
If they were no one would have noticed anyway; no one did the arcade in the past year.
It's just more noticeable now that they're actually worthwhile and not just a big waste of crowns.
